Finasteride is one of the most clinically proven treatments for male pattern hair loss (androgenetic alopecia). Studies show it stops further hair loss in 80–90% of men and leads to visible regrowth in around 65% of users after 2 years of consistent use. It works by blocking 5-alpha-reductase, the enzyme that converts testosterone to DHT — the hormone responsible for miniaturising hair follicles.
Most men notice hair shedding stabilising within 3–6 months of starting finasteride or dutasteride. Visible regrowth typically appears between 6 and 12 months of continuous use. Patience and consistency are essential — stopping medication will cause hair loss to resume within 6–12 months. Combining oral medication with minoxidil or PRP treatments can accelerate and enhance results.
Long-term use of finasteride (1mg daily) has been studied for over 10 years and is generally considered safe for most men. A small percentage (around 1–2%) experience sexual side effects such as reduced libido or mild erectile changes, which are typically reversible upon stopping the medication. In 2025, regulators updated safety information to note a rare association with mood changes — this should be discussed with your doctor, especially if you have a history of depression.
Generic finasteride 1mg in Malaysia costs approximately RM60–RM120 per box of 30 tablets, equating to RM2–RM4 per day. Branded Propecia (1mg) costs RM160–RM220 per box. Dutasteride (0.5mg, an alternative with stronger DHT suppression) costs slightly more. A doctor consultation to assess your hair loss pattern and prescribe the appropriate medication is required, as these are prescription-only medications in Malaysia.
Stopping oral hair loss medication will cause hair loss to resume, typically within 6–12 months, as DHT activity returns to pre-treatment levels. Finasteride does not cure hair loss — it manages the underlying hormonal cause. For continued benefits, treatment must be maintained long-term. Some patients transition to other hair restoration options (PRP, hair transplant) after achieving optimal density.
